  • Works great for cattle
Style: Fence Charger
I purchased one of these fence chargers late in 2018, and have been using it ever since to power around 4000 feet of fence with good results. We have a bull who was leaning on our barbed wire fence and even sticking his head through to "argue" with the neighbor's bull, but that all stopped after we installed a single strand of hot wire just inside the barbed wire fence. I really like the gauge on the front of case that provides an indication of the status of the system. From time to time the hot wire will get tangled with the barbed wire fence when deer jump over, and the gauge shows when the electric fence has gotten grounded on the metal fence. I simply locate the point where the hot wire is hung up on the barbed wire and pull it off. Having the hot wire grounded in this way does not appear to harm the fence charger at all. I used a 12-volt battery to power this fence charger until a couple of years ago, and now it is powered by a 12-volt power supply that is plugged into a 120-volt outlet. Both methods work well, but it was inconvenient to keep the battery charged up all the time. I drove in one 8-foot ground rod next to the fence charger and that seems to be working well enough for the grounding connection. Many recommendations call for three ground rods spaced 10 feet apart, but we're getting by with only one so far. ... show more

  • 0.7 watts (60mA)
Style: Fence Charger
I could not find actual current numbers before purchasing. It's better to use a 12V charger if you're planning to run on batteries. The idle current (no load) for most inverters is larger than the running current on this one! Current draw seems UNRELATED to load. That was a surprise. Same current drain whether you short the output or connect nothing at all. It charges a capacitor, discharges it through a transformer, and what happens on the other side of the transformer is irrelevant to input current. The meter on the front shows the output voltage of the last pulse: draw an arc (1/8 inch) and the meter goes to zero until the next pulse. I, like many others, wish the pulse interval was adjustable. I'd eagerly accept a higher current drain if I could up the pulse rate because I'm trying to protect against smaller faster critters. I also wish I could buy their higher power chargers with 12V inputs. Together that BARELY cost one star. (Almost unfair to reduce the rating but I can't get exactly what I want.) Usage note: The local rats are VERY cautious. Pest control companies will not place traps outdoors because they never catch anything. Stories abound that rats can sense voltage and not approach. Wrong. MY personal pest visited my test rig several times per night, but took over a week to work up the courage to step on a wire mesh baited with bird seed. The birds were quite happy to eat undisturbed from a bowl of seed inside a yard square mesh enclosure. Squirrels never even tried to get inside. I think the locals know about live traps and anything that looks like a trap deters them. Once the rat got comfortable with seeds on the mesh, I energized the mesh and another layer of mesh on top of a 1x4 board... with the controller (10 ft away) and the mesh both making clearly audible ticking sounds once per second. The rat took the bait, got shocked, rolled over, walked around unharmed. Hasn't been back since that one shock (all on my DVR so I'm sure). The pulse makes a pretty loud "tick". Don't sleep next to it. ... show more

  • Protecting our landscape during blackouts
Style: Fence Charger
After a few months, deer lost their fear or confusion of 3D fencing. Electrifying the outer strand has made all the difference in the world. The Parmak fence charger makes deer jump & run when they touch the hot wire. A 5W solar panel & a trolling battery maintain the protection, even during blackouts. You can hear it TICK while it's working. Tool less connectors are a welcome asset. ... show more

  • Received today, not in use yet, but item seems to have been tampered with
Style: Fence Charger
Disliked, looks like someone took a screw driver and opened case of Parmak 12 volt Fence Charger, see attached pictures, received today. Have used several Parmak Fence Chargers, both solar and stand alone 12 volt. Metal case units not plastic as this unit is. Usually last about 3 years or so, continue to use them because of price. Will install and try out this charger, but will run a silicone bead on seams top & side due to very slight gap at seam, will leave bottom without silicone in case of internal moisture accumulation to drain. Wish this one had the switch under meter to turn on & off. I will add a switch to my battery box. Will update before 30 day return window. I have a second unit that will be sold by & shipped by Amazon and compare the two. ... show more

  • Works on Deer to keep out of garden
Style: Fence Charger
I was looking for a DC charger that would keep the deer out of my garden. I have no AC power in that area. Before I purchased this charger I had tried several others but they were to weak. This one looked to have the power but had complaints about moisture and corrosion on the internal electronics. I ordered two chargers and when they arrived I noted that they had good strong cases. To guard against internal moisture I took some form-a-gasket used for autos and sealed the seams on the case as shown in the photo. I did not open the case. I just ran a bead and used my finger to spread it for coverage. I am on my second year and have had no issues with ether charger. I do have them simi covered from direct rain but they can get some moisture on them. They give a strong jolt and I have had no issues with deer in my gardens. I would buy again. I use the fiberglass electric fence rods from Tractor Supply to run the wire for the fence. For the battery I purchased a Marine/RV for power. They can be discharged further down that a normal car battery without harm. ... show more
